CVE-2025-63690Public exploitNetwork attack vector

Authenticated command execution via unsafe Quartz reflection

Published Nov 7, 2025 · Updated Nov 7, 2025

Remote code execution in pig-mesh Pig 3.8.2 and earlier allows remote authenticated users to run commands through Quartz task creation. The Quartz management function reflects over an attacker-selected class with a parameterless constructor and invokes a selected String-parameter method, allowing jakarta.el.ELProcessor.eval to interpret a command expression. Exploitation requires login and permission to create, start, and immediately execute scheduled jobs, after which commands run in the Pig server's context.
